That's useful for borderless need. I open several webpage to look borderless documentation. It's Very good!!

Great add-on !

Nice extension. Is it possible to implement alt + click, left + right click or something similar for activation?

It just works

Great extension...must have!

The extension used to hide the mac title bar on the standalone windows, but this has recently stopped working. Any ideas why?

Não faz nada de útil. Cria uma janela que não pode ser maximizada. Qualquer outro navegador faz melhor que isso.

Great add-on! Is there a way to customize the title of the new window? It currently starts with the URL - {title}

I use the WindowTitler add-on (https://addons.mozilla.org/en-US/firefox/addon/window-titler) to add a prefix to my Firefox windows, but the keyboard shortcut to bring up that extension doesn't work in these "popup" windows. Having a way to access that extension would be a workable way to (manually) fix the titlebar.

It is great! Exactly what was needed, thanks!

brilliant. all i need for my browser for "sticky" windows.

Perfect for Google Sheets and Docs to make them look more like real Windows apps.

Exactly what I was looking for! One click and I was done. Brilliant!

This addon has a huge potential! You should make that the windows automatically get miximized, pixel sizeing in the opitons not always do the work. Also, you should work on getting a full screen view, but without hidding the windows bar, so it looks really like a Web App. Hope you take this suggestion.

This worked littlebit better than others what makes the same here, so thank you :)

I wanted to pop out a music video playlist from youtube so I could have a small screen on my desktop. This add on allows me to to that. Thank you! :)
